INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".

Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).

Let's dig in:

Goroutines

Про токены, JSON Web Tokens (JWT), аутентификацию и авторизацию. Token-Based Authentication

Last major update: 25.08.2020

Что такое авторизация/аутентификация
Где хранить токены
Как ставить куки ?
Процесс логина
Процесс рефреш токенов
Кража токенов/Механизм контроля токенов

Direct copy of pre-encoded file:

$ ffmpeg -i filename.mp4 -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls filename.m3u8

First, add pry-rails to your Gemfile:
https://github.com/rweng/pry-rails

gem 'pry-rails', group: :development

Then you'll want to rebuild your Docker container to install the gems

This gist will drive you through creating a Docker 1.12 Swarm cluster (with Swarm mode) on AWS infrastructure.

Prerequisites

You need a few things already prepared in order to get started. You need at least Docker 1.12 set up. I was using the stable version of Docker for mac for preparing this guide.

$ docker --version
Docker version 1.12.0, build 8eab29e

You also need Docker machine installed.

	bash$ psql -d postgres ## connect to postgres
	psql# create database logger; -- create a database named "logger"
	psql# begin; -- start a transaction
	psql# \i log.sql -- load database
	psql# commit; -- commit the transaction
